Process controller ATR244 sets new standards for Pixsys ATR range of controllers. It stands out for the bright display which ensures optimal visibility and increased level of information for the operator beside a new scrolling Help function.

ATR244 relies on Pixsys flagship programming mode by NFC/RFID technology with dedicated App MyPixsys for Android devices (same already used for Pixsys signal converters and STR indicators) not requiring wirings and power supply, allowing quick set-up/updates on site.

Availability include a model with dual analogue input and dual analogue output for maximum flexibility of applications. It is possible to achieve two separate heating/cooling PID control loops in one device or to handle mathematical operations between two process values.

The outputs can be selected as command/multiple alarm modes/analogue retransmission. Serial communication standard is RS485 with Modbus RTU/Slave protocol.



User friendly, multimedia support and traceability

For the entire range of Pixsys products we provide technical support for installation, programming and operation via our online forum and via Skype.

The interface of the controller ATR244 ensures that the product is easy to use; operator is also supported byprogramming tools such asApp MyPixsys (for Android devices) and LABSOFTVIEW programming software.

Programming tutorial videos are available on our YouTube channel. As for the entire range of PIXSYS products, thanks to the QR code the traceability of the product is guaranteed for its entire life cycle; the information and documentation online can be also be accessed by reading the QR CODE that directs your mobile device to the product's technical specifications and verifies its warranty conditions.
